Iris-fixated intraocular lenses for ametropia and aphakia

Abstract

Implantation of intraocular lens with Iris-fixation is a safe, efficient and predictable surgical procedure, which empowers the refractive surgeon with singular capabilities. Among their advantages are the reversibility, preservation of accommodation and a broad spectrum of ametropic correction. This lens also appears to be a valid option, with a favorable complication rate, for the treatment of aphakic eyes without capsular support. This article is a review of iris-fixated intraocular lenses and considers their principal indications, complications, and outcomes.

The Artisan aphakia IOL presents a biconvex design with ultraviolet light filtration. The surgeon implants the IOL by placing it on the iris, centering on the pupil and clutching a fold of midperipheral iris stroma, without interfering with iris vascularization or the trabecular meshwork. They are marginally raised above the iris plane, except at the fixation points, preventing them from meddling with the normal physiology of the iris or angle structures. These IOLs are used to correct aphakia (a similar model is used to correct refractive errors) (14,24)
